Since Facebook opened up to the public, the Facebook-specific apps are coming out of the woodwork, and one of the better ones is Tixology, a good way to hook yourself up with some tickets to your favorite event.

Think of Tixology as a Craigslist for Facebook users; you can post tickets you want and/or have, and then fellow Tixology folks can respond. Unfortunately, only college-based accounts can use Tixology right now, but I expect that to change fairly soon. Any other Facebook apps you'd like to clue us in on? Let us know your thoughts in the comments.
